3. Remove the sensor and the sensor-switch.
Examination
1. Warm up the engine coolant temperature sensor by immersing it in hot water.
2. Check that the sensor resistance is within the specified limits.
Resistance:
- 90.5 ohm at 70°C
- 21.3-26.34 ohms at 115°C
Coolant temperature switch
Checking and installing the coolant switch-switch is the same as in the case of single camshaft engine.
